BACKGROUND

The present disclosure relates to an attachment for an implement such asa tillage tool.

SUMMARY

Implements such as tillage tools can be used to break up soil clods,remove weeds, and cover seed. Both shank style and disk blade styletillage tools can create soil profiles in the soil having convolutionsof laterally spaced hills and valleys commonly described as shank trackson shank machines or disk blade marks on disk style machines. Theseconvolutions of the soil can be undesirable to plant into, so variousharrows have been designed and utilized on shank style tillage machinesand on disk blade style tillage machines to level these convolutions outprior to planting. In high residue conditions, several of the currentharrow solutions in the market today either struggle to do a good job ofleveling the soil surface out or they struggle to flow residue evenlywhile leveling the soil surface. The present application provides aunique solution to level low to high residue seedbeds without creatingresidue bunching.

FIG. 1 illustrates one such possible embodiment. The illustratedembodiment includes a tractor 10 having a motor 11 for driving thetractor 10 and a plurality of tractor wheels 12 for supporting thetractor 10 on ground that is typically soil. A tillage tool 14 iscoupled to the tractor 10. The tillage tool 14 includes a frame 15having a main portion 15 a, a left-side or first lateral portion 15 b,and a right-side or second lateral portion 15 c. The tillage tool 14includes rows of disc gangs 16 and rows of wheels 17. The disc gangs 16are configured to create convolutions in soil such that the convolutionsare oriented substantially parallel to a direction of travel 19. A dualbasket attachment 18 includes a front basket 20, a rear basket 22, and acoupling bar 23. The coupling bar 23 couples the dual basket attachment18 to the back of the tillage tool 14. The illustrated front basket 20and rear basket 22 have a main section 20 a and 22 a, a left-side orfirst lateral section 20 b and 22 b, and a right-side or second lateralsection 20 c and 22 c. The aforementioned sections of the front basket20 and rear basket 22 are staggered. Other embodiments of the dualbasket attachment 18 can include fewer or more sections. For example,the tillage tool 14 may include only one frame portion 15 withassociated disc gangs 16 and wheels 17, and the dual basket attachment18 may include one front basket 20 and one rear basket 22.

In the illustrated embodiment of FIG. 1, the tractor 10 is generally infront of the tillage tool 14 and the tillage tool 14 is generally infront of the dual basket attachment 18 oriented in the direction oftravel 19. FIG. 1 also illustrates an example of the placement of eachfront basket 20 or front basket section relative to each rear basket 22or rear basket section. Each front basket 20 is generally in front ofthe associated rear basket 22 such that each front basket 20 traversesthe soil before the rear basket 22 during operation.

FIGS. 2 and 3 illustrate one possible embodiment of the dual basketattachment 18 in greater detail. The coupling bar 23 is coupled to theback of the tillage tool 14. The front basket 20 is coupled to thecoupling bar 23 by first arms 24 and the rear basket 22 is coupled tothe coupling bar 23 by second arms 26. The first arms 24 include a firstsection 24 a and a second section 24 b. The first section 24 a andsecond section 24 b are connected by a rocker bar 25 as shown in FIGS. 2and 3. The second arms 26 also include a first section 26 a and a secondsection 26 b. The first section 26 a and second section 26 b are alsoconnected by a rocker bar 27 as shown in FIGS. 2 and 3. The first arms24 are operated, respectively, by first hydraulic cylinders 28 and thesecond arms 26 are operated, respectively, by second hydraulic cylinders29. In some embodiments of the dual basket attachment 18, the hydrauliccylinders 28 and 29 can be controlled by a single hydraulic circuit.Other possible embodiments include each set of hydraulic cylinders 28,29 operating separately or any of the hydraulic cylinders 28, 29operating individually. The first arms 24 and second arms 26 regulatethe pressure at which the respective front basket 20 and rear basket 22press against the ground while in operation. The hydraulic cylinders 28and 29 can be operated by a control system within the tractor 10.

As shown in FIGS. 3 and 4, the illustrated front basket 20 is a knifeedge basket and includes six knife blades 30 held together by first endplates 31. Each knife blade 30 includes a knife blade tip 32 and a knifeblade side 34. The front basket 20 is arranged to operate in a passiveorientation such that soil is smoothed rather than thrown. Theillustrated front basket 20 rotates in the direction of arrow 35 inresponse to the movement of the tractor in the direction of travel 19(see FIG. 1). The passive orientation includes knife blades 30 arrangedsuch that the knife blade sides 34 touch the ground before the knifeblade tips 32 penetrate soil when operating in the illustrated directionof rotation 35. The knife blade tip 32 breaks up soil clods and levelssoil while the knife blade side 34 firms soil.

The illustrated rear basket 22 is a pipe basket (round bar basket)having eight pipes (round bars) 36 held together by second end plates37. Each round bar 36 further firms and levels soil. Other embodimentscan include fewer or more knife blades and round bars. Some embodimentsmay replace the round bars with flat bars.

FIG. 5 illustrates one possible embodiment of a tillage tool 14 with adual basket attachment 18 in operation. The illustrated knife blades 30are straight bars but can also be spiral bars in some embodiments. Theillustrated round bars 36 are spiral bars but can also be straight barsin some embodiments. The tillage tool 14 first moves over the soil andcreates disc blade hills and valleys that are generally parallel to theillustrated direction of travel of the tractor as indicated by arrow 19(some of the valleys are indicated with the reference 38 in FIG. 5). Thefront basket 20 then moves over the soil and reorients the disc bladehills and valleys (such as valleys 38) into knife-edge hills and valleys(such as valley 40) that are generally perpendicular to the illustrateddirection of travel. The rear basket 22 then moves over the soil andlevels the knife-edge hills and valleys (such as from valley 40 tovalley 42), resulting in complete removal of the valleys 38 that aregenerally parallel to the direction of travel 19 and substantial fillingin of the valleys 40 that are generally perpendicular to the directionof travel 19 as shown on the right side of FIG. 5 (see valleys 42). Insome embodiments, flattening refers to a reduction in the height of thehills and depth of the valleys 40 by about fifty percent to valleys 42but not necessarily to the extent such that the valleys 40 arecompletely removed from the soil. In some embodiments, the height of thehills and depth of the valleys 40 are only reduced by between abouttwenty five percent and about fifty percent. In some embodiments, thefront and rear baskets 20, 22 cause an overall reduction in height ofthe hills of between about sixty six percent and about seventy fivepercent.

The following tables illustrate two possible examples according to someembodiments of the present invention. Table 1 and FIG. 6 show a firstexample which includes dry, mellow soil with minimal residue that isworked by a gang angle of four degrees. The soil height after the diskgangs 16 have worked the soil is about three inches with hills 38 ahaving a height of about three inches above valleys 38 b. Theillustrated hills 38 a and valleys 38 b extend generally parallel to thedirection of travel 19. After the front basket 20 travels across thehills 38 a and valleys 38 b, then hills 40 a and valleys 40 b thatextend generally perpendicular to the direction of travel 19 are formed.The illustrated hills 40 a have a height of about three inches above thevalleys 40 b. After the rear basket 22 travels across the hills 40 a andthe valleys 40 b, then hills 42 a and valleys 42 b are formed. The hills42 a have a height of about one and a half inches above the valleys 42b. The illustrated hills 42 a and valleys 42 b extend substantiallyperpendicular to the direction of travel 19.

Table 2 and FIG. 7 show a second example which includes relatively wetsoil with standing corn residue that is worked by a gang angle of twelvedegrees. The soil height after the disk gangs 16 have worked the soil isabout six inches with hills 38 c having a height of about three inchesabove valleys 38 d. The illustrated hills 38 c and valleys 38 d extendgenerally parallel to the direction of travel 19. After the front basket20 travels across the hills 38 c and valleys 38 d, then hills 40 c andvalleys 40 d that extend generally perpendicular to the direction oftravel 19 are formed. The illustrated hills 40 c have a height of aboutthree or four inches above the valleys 40 d. After the rear basket 22travels across the hills 40 c and the valleys 40 d, then hills 42 c andvalleys 42 d are formed. The hills 42 c have a height of about one and ahalf to two inches above the valleys 42 d. The illustrated hills 42 cand valleys 42 d extend substantially perpendicular to the direction oftravel 19.
